Spicer 1310 Series Ford 8.8 Rear Pinion Flange Yoke Adapter for Jeep Axle Swaps (XJ, YJ, TJ)

Seamlessly adapt a heavy-duty Ford 8.8-inch rear differential into your built trail rig while retaining your factory-spec driveline using this genuine Spicer 1310 Series Flange Yoke Adapter. Specifically engineered to simplify the popular Ford Explorer 8.8 rear axle swap into classic Jeep Wrangler and Cherokee models, this premium adapter links the flat Ford four-bolt circular companion flange directly to your Jeep's standard 1310 universal joint layout.

Swapping an Explorer 8.8 rear end into a lifted Jeep is one of the most effective, budget-friendly ways to handle larger tires and rugged terrain. However, mating the Ford axle's flat mounting plate to a classic Jeep driveshaft requires precision geometry. This authentic Spicer component features the large Ford 3" x 3" square bolt pattern ($4.25\text{-inch}$ bolt circle diameter) and a exact $2.00\text{-inch}$ female center pilot hole, allowing it to center perfectly onto the 8.8 pinion flange. Built to eliminate driveline vibration, this heavy-duty steel forging provides deep rotational clearance, preventing universal joint binding when your rear suspension cycles through full trail droop and hard compression.

Product Highlights:

• The Ultimate Axle Swap Solution: Allows a seamless, bolt-on connection between a Ford Explorer 8.8-inch rear axle housing and a stock or aftermarket Jeep 1310-series driveshaft.

• Genuine Spicer Engineering: Precision-machined from ultra-durable forged steel to resist torsional twisting, high-impact trail shocks, and fatigue under severe load.

• Vibration-Free Alignment: Features a precise $2.00\text{-inch}$ female center pilot bore that seats flush against the factory Ford pinion flange to maintain absolute driveline concentricity.

• Optimized Clearance: Specifically dimensioned to maximize universal joint pivot angles, helping to protect your needle bearings from premature binding or failure on lifted off-road vehicles.
